A numerical model is developed to quantify the effects of hydrodynamics on heat and mass transfer during an absorption, for a laminar film flowing over a wavy wall column. First of all, the modelling is written for a single wave of the wall shape. Then, an experimental set up, composed of a CCD video camera, validates this model. Finally, the model is extended to an entire column. The results i...

Aiming at the construction of infill wall structural column are often used in artificial layer pouring method and top pouring back method, to improve the structure of wall column concrete pouring process, puts forward a new type of structural column concrete pouring machine. The application of this equipment, process worker can finish pouring filled wall structure column and tap filled wall str...

BACKGROUND The aim of this study was to explore the surgical treatment of transverse with or without posterior wall fractures of the acetabulum. MATERIAL AND METHODS We surgically treated 21 consecutive cases of pure transverse (7 cases) and with posterior wall (14 cases) fractures of the acetabulum. The anterior column fractures were firstly reduced, temporarily fixed through a modified Smith-...

Geological structures of Sima coal mine in Shanxi Province were analyzed to understand the control effect geological on occurrence coalbed methane (CBM) seam #3 mine. The CBM contents districts #2 and tested, effects buried depth, fault collapse column distribution content are studied. research results showed that: 1) average has a linear relationship with depth overburden thickness, but smalls...
